Started with a basic 3d scene
Initial rendering for concept proof
2nd proof. It looked bare and strange with gas pump on its lonesome
PSD layers with snow and various images
This is the base layer. I rendered the buildings separate
Levels adjustment layer. Trees and haze are on separate layers.
Background Layer. Added shop and background snow. The window textures are from photos outside traditional General Stores. You never really see them after the truck is in place.
Painted snow on shop and farm
Painted snow on truck, tires and gas pump.
I painted the foreground snow and fonts on separate layers in the final Illustration
